fixed bug with weighted disconnected graphs (#71) h/t @gi0na

• added install of oaqc to readme(#52)
• fixed grammar in Description (#53)
• made dynamic layout example reproducible (#54)
• replaced 1:length with seq_along (#55)
• added contributing guide (#56)
• added more tests (#60)

• fixed description of bbox in layout_with_stress
• fixed bug in layout_with_stress3D which only produced a 2D layout

restoring old seed after using stress layout

• added layout_as_multilevel() for multilevel networks
• added layout_with_stress3D() and layout_with_constrained_stress3D() for 3D layouts
• fixed crash in layout_as_backbone() when the graph has loops (#32)

Speed up of several algorithms

Details:

• added layout_with_constrained_stress()
• added fixed random seed for stress (stress is deterministic and produces same layout up to translation/rotation)
• speedup of layout_with_sparse_stress() and layout_with_pmds() by "smarter" distance calculation
• speedup of layout_with_sparse_stress() by using precomputed distances in layout_with_pmds()
• speedup of layout_with_stress() by dynamically switching to layout_with_pmds() during initialisation for large graphs

• BREAKING CHANGE: removed qgraph(). Now part of ggraph.
• POSSIBLE BREAKING CHANGE: layout_with_focus() now also returns the distance to the focus node
• changed filenames (doesn't have any effect on functionality)
• added layout_as_dynamic() for longitudinal network data
• removed gbp and scales dependency and moved oaqc to suggest
• edge weights are now supported in layout_with_stress() and layout_with_focus()
• added layout_with_pmds() (Pivot MDS for large graphs)
• added layout_with_sparse_stress() ("stress for large graphs")

• changed name from smglr to graphlayouts
• added layout_with_eigen()
• layouts can now be used directly in ggraph, e.g. ggraph(g,layout="stress")+...
• added documentation, examples and references
• added layout_with_centrality()
• added layout_with_focus()
• added reorder_edges() to reorder an edgelist to control the order of plotting edges
